Table 1. Basal locomotion rates and time to spontaneous reversals are unaffected in dopamine and glutamate signaling mutants.

basal locomotion rate
strain	n	body bend/min.
wild type	15	23.6±1.7
wild type (+ dopamine)	15	21.2±1.4
cat-2	15	20.0±1.3
cat-2 (+ dopamine)	15	21.2±1.3
glr-1	40	25.5±1.6
glr-2	40	25.3±1.7
nmr-1	40	26.4±1.6

See Materials and Methods for technical details. In all cases there was no statistically significant difference between any of the strains tested and wild type. Data are presented as mean ± S.E.M. The glr-1 allele used was ky176.
